Abstract

The invention discloses a device used for airtight lumbar puncturing and cerebrospinal fluid replacing. The device comprises a lumbar puncture needle, an injector and a connector used for connecting the lumbar puncture needle and the injector. A communicating device with four communicating pipes is arranged in the connector. The device has the advantages that functions are multiple, use is safe and convenient, the device is used for the lumbar puncturing and is good in airtightness and sterile, direction dividing operation can be achieved, the risk of intracranial infection caused by lumbar puncturing and intrathecal liquid injecting can be effectively avoided, the flow speed of the cerebrospinal fluid can be controlled, the risk of the formation of cerebral hernia can be avoided, intrathecal liquid injecting can be conducted through a side hole in the device and the injector, different medicine can be injected, the flow speed of liquid medicine can be controlled through a valve, the pressure in the medicine injecting process can be controlled through a pressure regulating valve, and intrathecal liquid injecting can be reasonably and safety conducted.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a device for airtight lumbar puncture and cerebrospinal fluid replacement. Background technique [0002] In traditional lumbar puncture, ordinary lumbar puncture needles are usually used for direct puncture. This puncture method has many disadvantages, such as poor airtightness, easy to cause infection, etc., and the injection speed is not easy to control, and intracranial pressure is difficult to monitor and control. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for airtight lumbar puncture and cerebrospinal fluid replacement, which solves the problems of poor airtightness, easy infection, difficult control of injection speed and difficult monitoring of intracranial pressure in current lumbar puncture and cerebrospinal fluid replacement devices. and control issues. [0004] The technical solution adopted ...
